A map of how Claude works, written by Claude: one token's journey, circuits researchers traced inside Claude models, how a route gets picked, what Claude cannot see about itself, and how to work with it. Built by Claude (Opus 5.5) in a single Claude Code session. This is not an official Anthropic page. Research findings link to their sources; the truth switch colors every node by how we know it.
